Answer 1

The ordered pair that is the solution to the system of equations is (4, -7)

Which ordered pair is the solution to the system of equations?

From the question, we have the following parameters that can be used in our computation:

y = 2x − 15

4x + 3y = −5

By substitution, we have

4x + 3(2x − 15) = −5

This gives

4x + 6x - 45 = -5

So, we have

10x = 40

x = 4

Next, we have

y = 2 * 4 − 15

y = -7

Hence, the ordered pair is (4, -7)
